Description Petr Bartos 2021-01-30 16:16:11 UTC 
SUMMARY

When splash screen is disabled, plasma starts however it takes long time before it starts applications in autostart, powerdevil and possibly others.

STEPS TO REPRODUCE
1. Disable splash screen
2. Restart plasma session

OBSERVED RESULT

Applications in autostart, powerdevil and possibly others take long time to start. plasma-ksmserver.service prints following:

led 30 16:58:22 NB0656 systemd[1645]: Starting KDE Session Management Server...
led 30 16:58:22 NB0656 ksmserver[1738]: Qt: Session management error: networkIdsList argument is NULL

ADDITIONAL INFORMATION

Might be also caused by some packaging/configuration problem as I am using this unofficial COPR repository https://copr.fedorainfracloud.org/coprs/mkyral/plasma-unstable
Comment 1 Mariusz Libera 2021-02-16 18:59:44 UTC 
I did experience the same thing but only after enabling systemd startup:
kwriteconfig5 --file startkderc --group General --key systemdBoot true

additionaly powerdevil stopped intercepring power button events so pressing the power button just shut down my laptop instead of displaying the logout dialog.
Enabling splash fixed the deylayed autostart but powerdevil still didn't work as expected so I had to go back to the non systemd startup:
kwriteconfig5 --file startkderc --group General --key systemdBoot false

Cannot reproduce. Are you able to reproduce this issue in Plasma 5.25 or later?
